1. FEATURE
SP resin is a new and multi-function epoxy base-solidifying agent
with the virtues of solidification, rigidness, improvement and
anti-inflammability. It is fit to use with acid anhydride family
solidifying agent and its binding force is 1~2 times stronger than
the single cid anhydride epoxy solidification, the anti-impact
strength is 50% more than the former and the solid substances’
inflammability proof can be improved as well.
2. MAIN TECHNICAL DATA: Title | Outer Appearance | Acid value | Viscosity | Heating degree | SP resin | Brown liquid | KOHmg/g(260~310) 120 oC/2h (<4%) | Coating #4 cup at 40 oC (10min/+/-30s) | 120 oC/2h (<4%) |
Add 0.5g HK-021 liquid acid anhydride (the actual test, increase
the heating and decrease quantity down to 2.24%) into SP 0.2 and
then test it. 3. APPLICATION
SP resin can be used in high-temp/low temp resistance binding, the
filling of resin base compound materials, insulation materials and
immersed oil motors and the sealing/filling of electronic
components etc. 4. SP RESIN APPLICATIONS
1) SP resin is a brown viscose liquid suitable to be used with
solidifying agent of acid anhydride and however it cannot be
utilized with amine series materials. We recommend the recipes as
follows: first mix well the 50% liquid acid anhydride, 20% SP
resin, then add 100% #618 epoxy resin evenly tossed after that you
can use it.
2) Solidifying Process
120 oC/2h + 150 oC/3h + 180 oC/1h, the binding shearing strength
(#45 steel strip test sample to be under sand blast) can reach
330kg/cm 2. It can approach over 350kg/cm 2 if added with CTBN to
improve the impact performance and inflammability dramatically. The
mentioned recipes’ OI value is at 22.3 and can be solidified at 180
oC/3h.
3) SP resin, if at the low room temperature will assume
gelatin-like and can be melt if heated appropriately. 5. SP resin is packed in paper drum with plastic drum inside and
10kg~15kg per package.
